The Seiko Vintage Stainless Steel Selfdater Automatic Men's Watch is a classic timepiece that exudes sophistication and style. With a sleek silver stainless steel case and matching band, this wristwatch features a dark dial and automatic mechanical movement.

I believe it is The vintage Seiko Sea Lion model.

please view photos carefully as there is marks and wearage

Works perfectly

The wrist strap is very small man's size.
